The Datsun 1200 uses a tradition recirculating-ball Steering Gearbox with behind-the axle linkage.

Terminology
- 1. Idler Arm. This bolts to the subframe rail on opposite side from the steering gearbox
- 9. Steering Gear Arm, a.k.a. "Pitman arm"
- 19,20. Side Rod, a.k.a. "tie rod". Left and right hand differ
- 12. Cross Rod, a.k.a. "drag link" or "center link"
- 21, 22, 23, 24. Side Rod Socket Ass'y a.k.a. "tie rod ends". There are four separate parts with left and right-hand threads. Each "socket" has a "ball stud", which is similar to a Ball Joint.
The six ball studs have a Filler Plug on the bottom of each. Replace it with a grease fitting and fill it during each periodic "lube, oil and filter".
Power Steering
Separating Ball-stud from Linkage
Separating the Steering Linkage for tie-rods, cross-rod, steering arm, knuckle arms or ball joints. To separate a rod-end/balljoint/ballstud, use one of these methods:
- Pickle fork and hammer
- Tierod-end joint puller
- Two-hammer method
- Prybar and hammer
CAUTION Never hammer on the threaded portion!
Datsun recommended the two-hammer method. Pickle fork is perhaps easiest but may damage the joint boot. Puller method is very nice.
WARNING Heating forged steering components is a VERY large no-no
Steering Gearbox Arm
Use the hammer methods or a gear puller.
Do not place a piece of pipe or wood on the steering rod and smack it hard with a big hammer. This can bruise/dent the worm in the steering box and compromise the box's smooth operation.
Two Hammer Method
- Remove the cotter pin & loosen the castle nut as far as the end of the ball-stud. This will hold the part from dropping all the way when the joint is popped apart.
- Hold a large hammer (e.g. 8# sledge) against one side of the part with the hole, and smack the other side with a 2nd hammer. The joint will pop out of the hole.
The first hammer is to absorb the blow so the part doesn't move.
NOTE: You have to smack it very hard while holding the stationary hammer at the same time AND not hit any other body or suspension parts. To make it easier, have an assistant hold the stationary hammer.
Sometimes people are not successful, usually because the hammer blow is not square to the stud axis and the energy is lost. But it will come out, regardless of condition, age, what-have-you, when done correctly. This is the method master mechanics use.
Pickle Fork
NOTE: Pickle fork may damage the joint boot. Great way to remove old bad parts, but the other methods are suggested for reusing the parts.
Pickle fork (wedge) fits many sizes of joints. For a Datsun, a medium size pickle fork is about right.
- Remove the cotter pin & castle nut
- Insert the fork between the two parts
- Whack the hammer very hard with big hammer. Use at least an 8# sledge. Better is a 12# or 16# hammer.
TIP: If possible, insert the hammer inline with the steering linkage, so that your hammer blow doesn't deflect the linkage sideways. Moving the steering wheel first will help line up the linkage to where you can hit it straight on.
Ball Stud Puller
You can use any small gear puller. A puller fits only certain sizes, but doesn't damage the grease covers. If using a generic puller, make sure the shaft when turned does not damage the ballstud threads.
Purpose-made ballstud puller:
- Remove the cotter pin & loosen the castle nut as far as the end of the ball-stud.
- Insert puller into correct position
- Turn puller nut with wrench or socket until the joint pops apart
- Remove castle nut fully
Lever and Hammer
- remove the split pin and nut
- Insert the lever (prybar, crowbar, etc.) to apply a medium pressure on the two pieces, as if prying them apart. But the leverage is only to apply pressure, NOT to actually separate them.
- While keeping pressure on the parts, using two hammers, hit opposite sides of the hole simultaneously. You don't need to use Big Hammers.
What you are doing is deforming the hole out of round for just a second which breaks the tapers bond from being jammed together, this will spit the ball stud off. You dont need to pound very hard, just keep tapping away.
